IPC: H01L29/74
Filed: 1978-04-26
Abstract: PURPOSE:To reduce gate firing current and achieve the improvement of commutation characteristics by cutting off the side line where a part of the gate firing current of the SCR part passes the diode part. CONSTITUTION:A mesa groove 9 deeper than the junction of a P layer 2 and an N layer 1 is created in the intermediate region III of the PB layer 2a of an SCR part I and the P layer 2b of a diode part II. The inside of the groove is insulstion-covered 10. This groove isolates the electrode 5a making contact to the surface of the NE layer 4 and a part of the PB layer 2a and the electrode 5a on the P layer 2b. The electrodes 5a, 5b are connected on the outside. The firing current IGT from the gate 7 is only the effective component IGTO and the small sideline current IGTS' flowing the PB layer 2a of the shortcircuit emitter part, thus the large effective component IGTO may be obtained with the small IGT. The carrier accumulated in the N layer 1b at the commutation owing to the presence of the region III is prevented from flowing into the NB layer 1a, whereby the commutation characteristics are improved.

Inventor: MORI TOSHIBUMI
IPC: G11B20/10
Filed: 1987-03-04
Abstract: PURPOSE:To prevent the occurrence of a defective magnetic disk device by inputting both the output of an index pulse generating circuit and the output delayed by a delay circuit into a selection circuit and outputting either of these outputs. CONSTITUTION:A circuit 1 detects an index pattern from a servo pattern, and its output 11 is inputted to a circuit 2 which generates an index pulse 12, and a circuit 3 then delays this pulse and generates a pulse 13. A circuit 4 usually selects the index pulse 12 to output. In case of a defective home address due to a flaw, the circuit 4 works by operating a selector switch belonging to the magnetic disk device to select and output the delayed index pulse 13. Therefore, the delayed index pulse is generated in a position evading a defective part of a data surface, and the home address is written on the non-defective part. Consequently, a format for data write and read can be performed, and hence the device can easily be delivered as a non-defective unit.

Title: Memory circuit
Inventor: OSAMI AKIRA
IPC: G11C11/417
Filed: 1978-04-27
Abstract: PURPOSE:To secure the same phase level for the data output as the writing data by using the input data signals and the writing timing which is activated only in the early writing cycle. CONSTITUTION:In the case of the early write cycle, node 5 and 6 are discharged by rising of the early write signal EW and changes into the earth potential. Thus, no information is tansmitted from the memory cell. With increment of timing OE, the voltage of node 2 rises almost in synchronization with OE through conducting MOSFETQ4. While node 3 is discharged with nonconducting MOSFETQ6 and Q7, and node 4 is kept at a dynamic low level regardless of increment of OE but changed to the earth potential via MOSFETQ14 with rising of node 2. As a result,  MOSFETQ17 conducts with Q18 turned nonconductive, thus a high level emerging at output DATAOUT. So is with DATAIN at a low level. Thus, such function can be obtained as to produce the same phase level at DATAOUT as the writing data.

IPC: G01N27/12
Filed: 1994-03-22
Abstract: PURPOSE:To prevent sensitivity lowering due to water vapor produced at the time when an oxide semiconductor is used as a carbon dioxide sensor, substantially eliminate the influence of the water vapor, and provide a carbon dioxide detector wherein precise carbon dioxide measurement can be performed. CONSTITUTION:While a carbon dioxide gas sensor element 1 is influenced by water vapor, it measures carbon dioxide concentration as a resistance R. A humidity detector 2 does not receive the influence of carbon dioxide gas and measures humidity as relative humidity H. A base line change width-measuring part 5a calculates a resistance RH of the carbon dioxide sensor element 1 at the time of carbon dioxide gas concentration being zero based on the output of the humidity detector 2. A correction factor calculation part 5b calculates a correction factor(f) at the relative humidity on the basis of the output of the humidity detector 2. An electric resistance change width-calculation part 5c and a carbon dioxide gas concentration calculation part 5d output a gas concentration corresponding value DELTAR0 on the basis of the output R, the resistance RH and the correction factor(f) of the carbon dioxide gas sensor element 1.

Title: Image defect detecting device
Inventor: YAMAZAKI MICHIO
IPC: G01N21/47
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To attempt the best way to positively detect the defect of a printed image in a short time. SOLUTION: The important area of an image can be identified by either of position information registered with an important area storage part 7, position information decoded based on PDL by a PDL decoding part 9 or position information imbedded in a shading. An important area identification part 8 reads image data corresponding to the important area identified by the position information from storage parts 11, 12. A comparison part 13 outputs an error signal to post the presence of a defect, if any non-conformity of the image data is found. As a shading area itself is an important area, it is possible to decide whether the image is defective by the defect of the shading itself without referring to original image data.
